I purchased a smoothieboard for my Delta build, and have just about everything running nicely, except for my fans…I am not able to control the P2.6 or P2.4 mosfets, they just stay on. P1.22 works just fine.

Additionally, P2.6 (the one which is set as default fan control in the config) seems to be under powered, while 2.6 and 1.22 are at 12v, 2.4 is at 3.3v.
